... for level II stability analysis of impellers. Such data are then incorporated into rotor-bearing vibration response models. Despite recent advancements in high fidelity, general modeling (i.e., three-dimensional viscous transient nonaxisymmetric model) of closed impeller rotordynamic forces, no such general...

...Baofeng Yang; Bin Li; Hui Chen; Zhanyi Liu; Kaifu Xu The clocking positions between the inducer and the impeller have a certain impact on the performance of the high-speed centrifugal pump, which however, is often ignored by designers. In the present study, three-dimensional numerical simulation...

... was evaluated numerically by using a CFD code. The “sudden-rising head effect” is confirmed to exist at a higher viscosity and a certain large surface roughness. The viscosity and roughness, which make a transition of boundary layer flow pattern in both the impeller and volute to the hydraulically smooth regime...
